(a) No later than six months after adoption of this chapter, all users shall install grease traps or interceptors designed to limit the introduction, contribution and discharge of greases into the Borough's wastewater collection system or POTW. Grease traps and interceptors with appropriate sampling or inspection points shall be installed at the user's expense whenever any user operates a commercial, industrial, or institutional cooking establishment. Grease traps and interceptors must have a minimum capacity of 1,000 gallons or more as required to affect a grease concentration maximum of 200mg/l.
(b) Alternative methods of compliance may be approved by the Borough if the user demonstrates that compliance with this chapter is impossible or impractical at the time of adoption of this chapter as a result of limited space. However, any such proposed alternative method of compliance will be required to meet the performance criteria specified in subsection (a) hereof, and the user must adequately demonstrate to the satisfaction of the Borough that the proposed alternative method will satisfy those performance criteria. In addition, any such alternative method must be cleaned at a more frequent interval than is required of grease traps and interceptors under subsection (e) hereof. Prior to approval of any such proposed alternative method of compliance, documentation of the proposed method's actual performance criteria must be submitted to the Borough for review and approval.
(c) Grease traps and interceptors may also be required in other facilities, as deemed necessary by the Borough.
(d) Upon prior written approval of the Borough, non-cooking establishment may be exempted from the requirements of this chapter after an inspection of the subject premises and submission of adequate supporting documentation, as deemed necessary, in the sole and absolute discretion of the Borough. At a minimum, such supporting documentation shall include: blueprints of the subject premises, a full and detailed description of the operations and activities at the subject premises, and a full and detailed list of all potential sources of grease at the subject premises.
(e) Users shall empty and service grease traps and interceptors to comply with the performance criteria in subsection (a) hereof as often as necessary, but in any event no longer than every sixty days. The Borough may require a specific schedule if deemed necessary. Under-the-counter types of grease traps and interceptors shall be cleaned at least daily and shall comply with the performance criteria in subsection (a) hereof. There shall be no reintroduction of wastewater back into the grease trap or interceptor unless said wastewater has been proven to contain 100 mg/l or less of grease. Under no circumstances shall the sludge or scum layer be reintroduced or discharged in the Borough's wastewater collection system or POTW.
(f) Users shall supply an adequate sampling point downstream of the grease trap or interceptor, prior to mixing with other sanitary flows, and accessible entry into each chamber of grease trap or interceptor. The minimum requirement for the sampling point shall be four inch vertical clean-out. The Borough shall have the right to inspect at any time and without prior notice.
(g) Users shall retain detailed records on-site for a minimum of three years reflecting maintenance carried out pursuant to this chapter. At a minimum, such records shall contain the following information: date of service, name of the employee involved, and a receipt reflecting all services rendered by the waste hauler providing the service.
(h) Users are required to keep the grease trap or interceptor free of inorganic solids such as grit, towels, gloves, cigarettes, eating utensils, etc., which could clog or settle in the trap or interceptor, thereby reducing the effective volume or capacity of the trap or interceptor.
(i) Users are required to ensure that all waste material removed from the grease traps and interceptors is disposed of in a manner that complies with all Federal, State and local statutes, rules, regulations, policies and ordinances.
(j) Except as provided herein, for a period of six months following the adoption of this chapter, no enforcement actions will be taken under this section for failure to achieve the performance criteria specified in subsection (a) hereof. If during such period, an obstruction of any of the Borough's sanitary sewer main(s) occurs and causes a sewer overflow, spill or leak or other event with any environmental impact, and such overflow, spill, or leak or other event may be attributed in part or in whole to a particular user, then the Borough will seek enforcement action under the Sewer Use Ordinance (Chapter 1040 of this Code of Ordinances), and/or the Industrial Wastewater Pretreatment Regulations (Chapter 1042 of this Code of Ordinances). For purposes of this section, an overflow, spill, leak or other event shall be deemed to have an environmental impact when such overflow or other event involves an amount of wastewater equal to or in excess of 300 gallons, or any amount of wastewater reaches any body or surface water.
